Page 203 - Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it? Whereupon are the foundations thereof fastened? or who laid the corner stone thereof; When the morning stars sang together, and all the Sons of God shouted for joy?
Page 155 - Sweet Swan of Avon ! what a sight it were To see thee in our waters yet appear, And make those flights upon the banks of Thames, That so did take Eliza, and our James...
Page 154 - To whom all scenes of Europe homage owe. He was not of an age, but for all time; And all the muses still were in their prime When, like Apollo, he came forth to warm Our ears, or like a Mercury to charm. Nature herself was proud of his designs And joyed to wear the dressing of his lines, Which were so richly spun and woven so fit As, since, she will vouchsafe no other wit.

Page 150 - Yet there happened, in my time, one noble speaker who was full of gravity in his speaking. His language, where he could spare, or pass by, a jest, was nobly censorious. No man ever spake more neatly, more pressly, more weightily, or suffered less emptiness, less idleness, in what he uttered. No member of his speech but consisted of his own graces. His hearers could not cough, or look aside from him, without loss. He commanded where he spoke, and had his judges angry and pleased at his devotion.
Page 314 - WHO is this that cometh from Edom, with dyed garments from Bozrah? this that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save.
